Sync works great in firefox. For perfect sync, you may need to press enter/click the go button (refresh works too, but less good.) Works pretty good in IE too. Sorry folks, it's been said before.. you can't sync a YTMND perfectly for everyone.

Andromeda is set to hit the Milky Way, but the collision would resemble a mixing of viscuous liquids. (Aka galaxy would get denser, yes.) Also, since some of you actually take this seriously, allow me to officially say: THIS YTMND = SATIRE/PARODY. Also c*cks.

mattermaio, do you just take information you hear, true or otherwise, and just spew it out like a volcano with diarreah? Yes, the universe is expanding, but those same scientists say that these two PARTICULAR galaxies are going to collide. duh.

if we can apply an inverse anti-graviton beam to the galactic core or the andromeda galaxy, it should cause the entire thing to disintigrate. However the only way to create enough anti-gravitons is to simotaniously fire a tachyon burst in the around the anti-graviton beam, so as to create a tachyon flux that would allow the gravitons being emitted by the Andromeda galactic core to be rerouted into anti-gravitons moving toward the center of Andromeda.

dude! u guys! ill still 5 it but this is all wrong- the stars and planets are so spread out in each galaxy, that there is almost a non-existant chance that even two stars would collide. its like think of a very very wide mesh door or something, and throwing sand through it. if the holes in the mesh are big enough, most of the sand wont even touch it!

Galaxies do collide. The universe isn't expanding at a perfectly uniform rate and in perfectly opposite directions. Here's some proof: http://hubblesite.org/hubble_discoveries/hstexhibit/galaxies/crackup.shtml

Pack your bags folks, we're takin a vacation!
Anyway, the sun will burn out in about another billion years so the earth and hopefully the people of the future will be long gone before then.. Unless we're all nuked...

Also, galaxies collide with each other quite often, but we dont see them cause they are so far away. We see the results of them but its not really anything disasterous, the planets and stars are so spread out that almost nothing happens if you were on a planet in one of those galaxies. What you would see is something like the milky way as close and as bright as the moon.

About two million light years (20 billion billion kilometers) away lies the Andromeda Galaxy, a spiral galaxy similar in size and shape to our Milky Way. Current measurements suggest that, in about three billion years, the Milky Way and Andromeda galaxies may collide. What will happen? The stars in the galaxies, our Sun included, will probably not hit each other, but the galaxies' mutual gravity will probably pull, twist, and distort them until, about a billion years later, a new elliptical-shaped galaxy is

Aorry, you fail to realize that the space between stars in a galaxy is vast. Andromeda and the Milky Way are liable to pass through eachother harmlessly. It might even cause both galaxies to merge into a larger galaxy. This isn't a disaster. Unless you're that stellar 5% that either gets slingshotted out of the galaxy into the black, or actually collide with a star. This isn't as big of a deal than it sounds.

Even if the collision were more violent than a long, drawn-out mixing of two different food colorings sloshing together in water, I seem to recall that the Milky Way has a good 750 million solar masses on Andromeda. We'd be the clear victor. :P

Good Work, as galaxy collisions are a very interesting topic in current research! I made a simulation of this event for my Carnegie Mellon Extragalactic Astrophysics class using roughly 2:1 ratio DM Halo particles to luminous matter particles by way of Fortran gravity treecode from Princeton. View @ http://soundutensils.ytmnd.com/ and let me know what you think!

There's two possibilities. One is that Earth and our solar system will swing safely out of the way or Earth basically goes boom, along with a few other billion stars. Well that would happen anyways but... nevermind. SCIENCE RULES!

well lets see, more then likely in 3-4 billion years we will have killed ourselves anyway, so worring about this crap now is like wondering if dark matter really exists or if we can use modified newtonian dynamics to explain problems with gravity in the univers on a large scale.

Yes, andromeda and milky way "collide in ~3 billion years but the density of the ojects is so small that barely any matter will collode! The sun is 5 billion years old (earth 4,5) and will explode in 5 billion years anyways.

Lol... funny... but collisions of galaxies is not a catostrophic event... as a matter of fact no stars will probably colide even when the galaxies "colide" because the stars are lightyears away from each other. The only thing it could maybe do is throw a planet or 2 out of orbit and make all the stars change positions instead of a neat little spin. The chances of a collision with our planet in a galaxy collision is (laugh) astronomical.

Check it yourself

Oh, and there doesn't have to actual collision of matter for this to screw us... the massive changes in gravity could shoot our system out of the galaxy or alter Earth's orbit. Plus there may be huge changes in the local radiation levels.
